For one, stylus precision is not necessary for a smart phone. That's kinda why the stylus went away back in the days of Palm devices. Second, it's not actually that precise. And from a few reviews on the Note2, people are complaining that the stylus is overcomplicated and an unnecessary gadget.

There's a reason why nearly every other mobile device has abandoned the sylus as a reliable input method.

I agree with this. For me it's a very bizarre phone, and a weird success story for Samsung. I could see it being useful on a tablet, but by all accounts, the 10.1 note is very weak.
